It is generally not recommended to use NFS storage for Elasticsearch, and if you do you need to check that [it is set up and mounted correctly](https://www.elastic.co/guide/en/elasticsearch/reference/8.6/modules-node.html#_node_data_path_settings).

hi ...because don't have external storageclass ..  
volume claim templates in the values.yml created pvc ... pv automatically created and bound with pvc .. i think ....hence mounting with volume is no issue ..
